Application of Computerized Switch for Domestic and Industrial Appliances

Abstract

This study was conceived out of the curiosity to appreciate automation and harness the possibility of controlling numerous appliances with a single remote control. It aimed at developing a computerized wireless switch using Infrared Technology capable of controlling the bi-directional flip-flop and push-pull switches of some household and industrial appliances such as fans and energy bulbs in order to reduce the stress associated with manual switching of these appliances. This study is designed based on the working principle and properties of Infrared Light, the ground on which remotes for home electronics are built. To achieve this objective, an ATMEG328p microprocessor was used to interface the TSOP1738 Infrared Receiver and the other components of the circuit on a breadboard or project board as a prototype. The whole system is composed of three units which are independently built as the Object-Oriented Programming paradigm is employed. The units are: the transmitter (a handheld universal remote); Control or Receiver (embedded processor) and the household or industrial appliances to be controlled. Emphasis was on the Receiver and controller unit because they formed the pillar of the automation. The system's implementation showed higher performance in terms of effectiveness, precision, and dependability, and controlled the household and industrial appliances at a distance of 10 meters.
